1.2MHz,High Efficiency Boost White LED Driver

SL6607


GENERAL DESCRIPTION

The SL6607 is a step-up converter designed for

driving up to 7 series white LEDs from a single cell

Lithium Ion battery. The SL6607 uses current

mode, fixed frequency architecture to regulate an

LED current, which is measured through an

external current sense resistor.

The SL6607 includes under-voltage lockout,

current limiting and thermal overload protection

preventing damage in the event of an output

overload.

Optimized operation frequency can meet the

requirement of small LC filters value and low

operation current with high efficiency. Internal soft

start function can reduce the inrush current. Tiny

package type provide the best solution for PCB

space saving and total BOM cost.
